[Features]· The pin located at the center of the star-shaped hole does not allow normal 6-lobe wrenches to be inserted.· Torque transmission is good, meaning that it will not cam-out and that workability is excellent.· The screw is conical in shape. Ideal female thread machining and screw-in by low torque is possible.
